WINDING OF YARNS Filed Jan. 22, 1947 Patented Apr. 17, 1951 UNITED}STATES PATENT o F'F'ICE This invention relates to the" windi'ngof yarnsand 'particularly'to the beaming of yarns on warp beams with orwithout'end flanges forsupporting the ends of the yarn mass Wound onthe beam.

In the beaming of yarnsit is sometimesthe practice to reinforce the endpo'rtionsof the yarn mass by the use of beaming collars, or strips ofpaper that are reinforced by' the application along" one edge of a stripof thi ckermat'erial such as cardboard of a width less than the widthofthe paper. The paper is-insertedbetween' adjacent layers of yarn atintervals throughout the winding of th'e'beam in such away thatthecardboard strip extends beyond the end portion of the yarn masswhiletheunreinforced part of the widthof the paper is'bound in by the'-adjacent layers of yarn as they are wound on the beam. The strips areinserted at'such intervals that the thickness of yarn wound on the beambetween the insertion of adjacent strips is equal to the thickness ofthe cardboard strip so that the cardboard strips buildup intoa soliddisc at-the end of the-yarn mass of a radiu equal to that of the yarnmass; Ithas been found; however, that notwithstanding the added bulk ofthe thin pa er that is included Within the yarnmass; theen'ds of theyarn mass are apt" to become sunken as compared with the main body-ofthemass. Tliisis mainly due to the shuffle or slight traversing of thewarpsheet to and fro along the'le'ngth' of the beam duringwinding,which'is'doneto ensure the solidity and stability of the yarnma'ss'wo'und on the beam.

In accordance with the presentinvention; a form of beaming collar inwhich this disadvantage is overcome and which possesses other advantagescomprising a strip of thick pliant material such as cardboard faced onboth sideswith a thinner material such as paper; the thinner material onboth sides projecting beyond one edge of the thicker material but todifferent distances; When a beaming collar of this construction is incurporated in the yarn mass during beaming'in such a way that the thickmaterial lies justoutside the end of the yarn mass; the thinnermaterial; which is included in the yarn mass, not only aug' ments thebulkines's of theyar'n at the end of the yarn mass toa greater'extentthan'ifa' single layer were employed, but is also graduated in thicknessby reason of the fact that one strip of thin material projectsbeyond theother. In this w'ay'the falling off of the density of yarn at the endsof the yarn mass is compensated for in a way that closely corresponds tothe gradual way in which the density falls 0111- Claims.

the paper projecting from each side of th'e's'trips' is folded over thestrips towards the middle. The double strips 5 and Bare then passedbetween forming rollers 24, 25, the upper roller 24 being a resilientroller, while the lower roller 25 is formed with a central enlargedportion 26 fitting into the space between the strips Sand creasing themiddle portion of thepaper strip 6 round the inner edges of thecardboard strips 5 and into contact with the roller 24. Acircumferential projection round the middle of the roller 25 cutssubstantially through the paper so as to form a line along which the twohalves can be readily separated. The product is then rolled up on a roll21, on which it is allowed to remain ,until dry, so that the form givento it between the rollers 24, 25 and on the roller 21 is permafnentlyset. When dry, the roll may be cut through along a radial line to form a.set of double collars for use in winding a beam of appropriate size (i.e., one with external and internal diameters substantially equal tothose of It is ,not, however, essential that the previously fixedcurvature of the collar should exactly match the curvature it will adoptin the wound beam. Accordingly, it may be more convenient to wind theassembled strips into a coil of larger diameter than the beams for whichitis to be used, and to cut the collars from the coil in appropriatelengths when required.

The beaming collars according to theinvention may be employed as thesole support for the ends of the yarn mass wound on the beam, the yarnmass being also reinforced by fullwidth beaming paper inserted atintervals between adjacent layers of yarn on the warp beam and extendingacross the full width of the warp. Indeed the invention contemplates theprovision of a full-width beaming paper reinforced at both edges bystrips of cardboard or like material, round the outer edges of which theedges of the paper are turned over so as to project inside the inneredges of the strip. The collars may also be employed, however, inconjunction with a beam flange and as separate collars without the useof the full-width beaming paper. In this case, by the provision ofbeaming collars having difierent widths of cardboard, the necessity fora fine adjustment of the position of the beam flange is obviated.Consequently, a beamwhose flanges have only a coarse adjustment or noadjustment at all may be used, and the expense of providing for a fineadjustment is avoided."

The manner in which the beaming collars described above with referenceto Figure 2 may be employed in beaming is shown in Figure 4, in whichthe yarn mass 30 is wound on a beam 3| and compressed between flanges32. Between the end of the yarn mass 30 and the flange 32 are dispersedthe strips l0, inserted at intervals during winding so that the paperflaps, are incorporated in the end of the yarn mass 30, the double flapentering into the extreme end of the yarn mass as at 33 while the singleflap extends further in as at 34. The collar is chosen as having a widthof cardboard approximately suflicient to fill the space between the yarnmass 30 and the flange 32, the crushing of the lip l4 provides for sometolerance in this respect, and also prevents any stray turns of yarnlodged between adjacent beaming collars slipping between the collars andthe flange 32.

Instead of using cardboard of 1 inch or A; inch in width other widthsmay be employed, for example a range consisting of 1 inch, 4-inch, inchand i -inch with a correspondingly narrower paper 'e'. g. 7 inches, 6inches, 5 inches and 4 inches so'that, where a flanged beam is requireda set of collars having strips of cardboard of the appropriate width canbe selected.
